Multiple sclerosis (MS) is a multifactorial neurodegenerative disease. Low levels of vitamin D are risk factor for MS and alterations in the receptor (VDR) might be as well. This study aimed to evaluate whether VDR rs731236 (Taq-I) rs4334089 (HpyCH4V) gene polymorphisms protein expression associated with severity. Vitamin plasma were analyzed group patients. Additional analyses patients differe...

systemic lupus erythematosus (sle) is an autoimmune disease in which polymorphisms within the human leukocyte antigen (hla) region have been associated to its etiology. we conducted this study to compare the hla-dqb1 allelic sequence variation among sle patients and controls in the northeast of iran. genomic dna of 40 sle patients and 83 healthy controls were amplified by polymerase chain react...

Background: Tumor necrosis factor-beta or lymphotoxin-alpha (LT-α), IL-4 and IL-10 are determining factors in immunity against BCG.  Allelic polymorphisms in the regulatory regions of their genes affect the rate of cytokine production and therefore, the host’s ability in BCG containment. Objective: To study the prevalence of –590 (C/T) and –592 (C/A) allelic distribution of IL-4 and IL-10 promo...

background:it has been hypothesized that genetic factors other than histocompatibility disparity may play a role in predisposition to developing chronic myelogenous leukemia (cml). in this regard, th1 and th2 cytokines and their gene polymorphism seems to be important. overall expression and secretion of cytokines is dependent, at least in part, on genetic polymorphism (nucleotide variations) w...

Background: The Human Leukocyte Antigen (HLA) is the most polymorphic region in human genome. Moreover, HLA haplotype frequencies are largely used in transplantation, the treatment of autoimmune diseases, and population-based studies. The present study aimed to determine HLA-A, -B, -DR alleles and haplotype frequencies in 88 unrelated donors of Iranian Gilak ethnic group, by Polymerase Chain Re...

This study was performed to investigate two polymorphic sites from Cyp19 gene (PvuII and MspI) and one polymorphic site from ERα gene (SnaBI) in four cattle breeds including Mazandarani, Taleshi, Sistani and Simmental. In overall 278 samples for CYP19 and 206 samples for ERα marker sites were genotyped using polymerase chain reactionsingle-strand conformation polymorphism (PCR-RFLP) procedure. ...

Background: β-thalassemia as a hereditary disease is defined as defective synthesis of   β-globin chains, resulting in erythropoiesis abnormalities and severe anemia. Different studies have shown that cytokines and cytokine gene polymorphisms play a major role in the pathogenesis of   β-thalassemia. Single nucleotide polymorphisms (SNPs) within the promoter region or other regulatory sequences ...
